FOR REQUIREMENT, SPECIFY IN ORDERDESCRIPTIOND eluge Valve is known as a system control valve in a deluge system, used for fast application of water in a spray system.

3 Deluge valve protects areas such as power transformer installation, storage tank, conveyor protection and other industrial application etc. With the addition of foaming agent, deluge valve can be used to protect aircraft hanger and inflammable liquid OPERATIONHD Deluge Valve is a quick release, hydraulically operated diaphragm valve. It has three chambers, isolated from each other by the diaphragm operated clapper and seat seal. While in SET position, water pressure is transmitted through an external bypass check valve and restriction orifice from the system supply side to the top chamber, so that supply pressure in the top chamber act across the diaphragm operated clapper which holds the seat against the inlet supply pressure, because of the differential pressure design.

4 On detection of fire, the top chamber is vented to atmosphere through the outlet port via opened actuation devices. The top chamber pressure cannot be replenished through the restricted inlet port, and the upward force of the supply pressure lifts the clapper allowing the water flow to the system piping network and alarm , 2022HD 235 PAGE 2 OF 16HD FIRE PROTECTPVT. DESCRIPTIONThe trims are functionally termed as Dry Pilot Trim, Wet Pilot Trim, Electric Trim and Test & Alarm Trim as per the method of actuation of the deluge functionality of these trims are described below:a) DRY PILOT TRIM (PNEUMATIC RELEASE)Dry pilot operation uses a pilot line of closed Sprinklers/ QB Detectors containing air under pressure, located in the area to be protected.

5 It requires regulated dry air supply with main supply point through restricted orifice. The air pressure to be maintained as specified in the catalogue of Dry Pilot Actuator (HD 252). The pilot line is connected to air inlet side of actuator. The top chamber of the deluge valve is connected to water inlet side of actuator. When there is an air pressure drop, or due to release of any of the releasing device on detection of fire, the diaphragm of actuator is lifted and allows the water to drain.

6 This releases the water pressure in the top chamber of the deluge valve, allowing the deluge valve to open and water to flow into the system piping & alarm devices. Recommended air supply pressure for dry pilot trim system is User must install non return valve at air supply connection to deluge valve trim. In dry pilot trim, an actuator (DPA) is provided. An optional Pneumatic Reset Device (PRD) can be provided, which acts as a manual reset device in the dry pilot ) WET PILOT TRIM (HYDRAULIC RELEASE)Wet pilot operation uses a pilot line of closed Sprinklers/QB Detectors containing pressurized water, supplied through the upstream side of the Deluge valve, through a restricted orifice.

7 Due to release of any one of the releasing device, the water pressure in the top chamber of the Deluge valve drops and the Deluge valve ) ELECTRIC RELEASE TRIM To actuate a Deluge valve electrically, a solenoid valve is provided to drain the water from the top chamber of the Deluge valve. A pressure switch is provided to activate an electric alarm, to shut down the desired equipment or to give Tripped indication of the Deluge valve. In addition to this a pressure switch can also monitor Low air pressure and Fire condition when used in dry pilot air ) TEST AND ALARM TRIM This trim is supplied with a test valve provided to test the normal operation of the sprinkler alarm bell.

8 The sprinkler alarm can be supplied additionally, which bells on actuation of the Deluge ) DRAIN AND DRIP TRIM This consists of main and system drain valve in addition with drip MODEL DESCRIPTIONMOUNTINGSCHEMATIC T- WBasic Wet Pilot TrimVerticalSchematic 1ET-DBasic Dry Pilot TrimVerticalSchematic 2 ETW-TBasic Wet Pilot Trim with Test & Alarm TrimVerticalSchematic 3 ETD-TBasic Dry Pilot Trim with Test & Alarm TrimVerticalSchematic 4 ETW-DBasic Wet Pilot Trim with Drip & Drain TrimVerticalSchematic 5 ETD-DBasic Dry Pilot Trim with Drip & Drain TrimVerticalSchematic 6N T- WBasic Wet Pilot Trim
